Further, since the escape portions 49, 49 are formed in the second bracket 42, the display panel 20 can be opened to the horizontal direction without abutting on the bent portion 39a of the top plate 39, and the first and second display panels can be opened. Holes 45, 45 in brackets 41, 42
Since the support bar 50 can be inserted and the display panel 20 can be held horizontally by aligning the support rods 46 and 46, the maintenance and inspection work becomes easy. Lighting unit 31 for backlight
By using a fluorescent lamp generally used as the illumination lamp 33, the display panel 20 can be opened and replaced easily. In addition, since the rear reflector 32 and the front reflector 34 form a box surrounding the front and back of the illumination lamp 33, and the surface is painted white, the reflection efficiency can be increased and the brightness can be improved. There is no shadow which tends to occur on the display surface due to the mounted components,
And protects the naked part of the body from damage during maintenance work and the like. In addition, since the indicator lamp 24 is housed in the cylindrical portion 20d formed on the back side of the display panel 20, even if the indicator lamps 24 are provided close to each other when switching and displaying, the light leaks from each other and affects others. It becomes easy to see without. Since the speaker 25 is housed in the case 36 and is attached to the downwardly inclined surface 20f formed downward of the display panel 20, it is possible to prevent infiltration of rainwater and the like, and to effectively output sound toward the front side. it can.

In the above-described embodiment, the description has been made centering on the display panel 20 at the center. However, the electronic device is mounted, and the display panel 14 is rotated by the butterfly plate 40 so as to face the opening 38 on the front side of the housing of the display case 14. The present invention can be applied to the display panel 20 which is freely provided. Although the first and second brackets 41 and 42 of the butterfly plate 40 are formed of a metal plate material, the first and second brackets 41 and 42 may be formed of a metal material having a structure sufficient to support at least the weight, and the shape and size can be arbitrarily formed. .
